This is a 5V 4-Channel Relay interface board, Be able to control various appliances, and other equipments with large current. It can be controlled directly by Micro-controller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic)

  • 1. Maximum load :AC 250V/10A, DC30V/10A
  • 2. SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA
  • 3. the module voltage 5V
  • 4. each channel module can be set high or low triggered by jumper
  • 5. fault-tolerant design, even if the control line is broken, the relay will not operate
  • 6. power indicator (green), 4 relay state indicator (red)
  • 7. interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient
